Webdynpro ABAP Scenario

Hi,
Can we develop a WD ABAP application on system1(ECC 6.0) which has to access standard,custom infotypes on system2 (ECC5.0) process/update them.
Can we use EP 6.0 to display the WD ABAP application as an iVIew.

Hi,
Yes you can do, you have to develop your WD ABAP application on system1(ECC 6.0) using BAPI call to access standard,custom infotypes on system2 (ECC5.0) process/update them.
try this way it will you.

User Roles & Authorization to run 'WebDynpro ABAP Application scenarios'

Hi All,
I am developer and my user ID is having developer roles, so when i am testing
'WebDynpro ABAP Application scenarios' it is working fine.
Problem is when I am executing with enduser portal WWID's (i.e. WWID's are also defined as sap
user), 'WebDynpro ABAP Application scenarios' giving me dump in screen & in ST22.
Pls guide me what roles or authorization we need to assign to user ID's
who can use 'WebDynpro ABAP Application scenarios'.
URL for Webdynpro application is like : https://xxxx.yyyy.zzzz:/sap/bc/webdynpro/sap/ZPA_EXTENSION_U?ZDATA=10028705591320090406

What happened?
    Error in the ABAP Application Program
    The current ABAP program "CL_WD_ADOBE_SERVICES==========CP" had to be
     terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "PARSE_XML_SCHEMA" "(METHOD)", nor was it propagated by a RAISING
     clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component.
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.

Need expertice opinion on WebDynpro ABAP vs FPM for heavy custom apps

Hi Experts,
I have a lot of custom UI development,.for external users in SAP. Most of these applications can be simply developed using WebDynpro ABAP framework. If I do the same development using FPM framework I may need to do lot of reaseach espcially controling the UI behaviours like hiding, changing table cell colors based on the data, manipulating the UI behavior in the runtime, lot more like this.
The question I have is , which one is the right tool for my development FPM vs WebDynpro ABAP, what is the value in building the same apps in FPM rather then WebDynpro ABAP? If I develop these apps in WebDynpro ABAP does my client loose any new capabilities in he future releases? are any other drawbacks?
The challenge i see the FPM Feeder classses doesnt have lot of interfaces other then few like ( IF_FPM_GUIBB_FORM, IF_FPM_GUIBB_FORM_REPEATER,IF_FPM_GUIBB_LIST,IF_FPM_GUIBB_SEARCH,IF_FPM_GUIBB_TREE,IF_FPM_GUIBB_LAUNCHPAD )
to extend more custom UI functionalities, and the other thing I may need to invest lot of time in reseacrhing and analysing the framework events etc....Please can you shed some light on it and put me in right direction.
Appreciate your time and help.
Thanks
Krishna

Hello Krishna,
the whole story revolves around reusability and abstraction, extensibility atleast in this context.
FPM offers more abstraction than Webdynpro. i am sure we all appreciate the standard webdynpro components for ALV, Value help, as this is something we could reuse and if we build our components that it manipulates itself with the help of configuration, customization and personalization.
So all the Standard SAP Dev could be enhanced (not modified) by simple, configuration, FPM is built around this concept.
So if you want to do custom development, which could be extended for your different customers with minimal efforts, you could go for FPM.
So here are some takeaways
1) FPM offers more abstraction than Webdynpro
2) FPM offers more reusability
3) Say manipulating the UI behaviour and say some customers wants view1 first and other doesnt want view 1 and wants only view 2. so in FPM you could simply do it with different configuration. and with Webdynpro, you need to manage this dynamically based on certain application parameter or you may end up copying certain comp,,or you use different usage,,,,and you could calibrate this.
Regarding limitation with FPM interfaces, could you explictly share what custom development you intend to do and in worst cases, you could always use freestyle UIBB,, which is webdynpro abap
in that scenario, atleast wiring, application config(app parameter, combination of webdynpro, with thier respective config),,could be reused.

How to call the RFC from R/3 to SRM, when we use webdynpro abap? (Urgent)

Hello
We use SRM Server 5.5 with classic scenario.
We want to call RFC in R/3 from webdynpro ABAP.
How can we do that?
We are developing the web report using webdynpro abap.
So we need some of R/3 data such like PR(EBAN)and PO(EKKO,EKPO).
When user choose the search parameter, report diplay the Shopping cart, PR and PO data on webdynpro. So we call the R/3 RFC to display the PR, PO data.
But I tired to call the RFC in R/3, We could not call it.
How to call the RFC from R/3 to SRM, when we use webdynpro abap?
Thank you,
Best Regards,
SH.

Hi
Please look at the following threads as well ->
WebDynpro in SRM
BAPI's /RFC's in SRM
BAPI to Change Shopping Cart by RFC
SRM60 and webdynpro
Webdynpro Services Exception
WebDynpro using BAPI has an error
SRM60 and webdynpro...
SAP uses META Function modules in SRM to get data from R/3 back-end.
For getting Purchase requistion data, use the function modules ->
META_REQUISITION_CHANGE Change purchase requisition
META_REQUISITION_CREATE Create Requisition
META_REQUISITION_DELETE Delete/close purchase requisition
META_REQUISITION_GETDETAIL Display requisition details
META_REQUISITION_GETITEMS Display requisition items
META_REQUISITION_GETRELINFO Get Releasease Info for requisitions
For getting Purchase order data, use the function modules ->
META_PO_CREATE Create purchase order
META_PO_DELETE Delete reservation
META_PO_GETDETAIL Display purchase order details
META_PO_GETITEMS Display purchase order items
META_PO_GETRELINFO Display purchase order release information
Hope this will definitely help. Do let me know.

Anonymous user Unbale to access an WebDynpro ABAP iView

Hi,
I have developed an application using webdynpro ABAP and integrated that into portal.
For this webdynpro application i have to create an iview, assigned it to a page, assigned this page to a custom role. I also set Authentication to anonymous for the page and iView. Assinged the custom role created to anonymous Group.
But while running it i am getting an error "An exception occurred while processing your request. Send the exception ID to your portal administrator. Exception ID 04:55_25/10/11_0047_14739050"
When I checked the log, it shows the error as "Deprecated scope of type SERVERSESSION_AT_LEAST_ONE_APP_SCOPE is used! Please replace the usage of scopes with new
mechanism based on "Cross application session communication API".
I also checked the note 1031159 and changed the configurations accordingly but getting the same above error.
I am on EP7.3 version.
Please guide me to move further successfully in showing the webdynbpro abap applicaiton to anonymous user.
Thank you.

Hi,
I'm also working on EP7.3 and R3 WD4A integration. But I just can't find any WD for ABAP from whithin EP7.3 wizard.
I tried to create the WD4A iview by right-clicking a PCD folder and then "New"->"iView"->"iView from remote source" to get a search screen. I choose a system alias (point to bk web as), use "*" as application id, and pick "WebDynpro for ABAP" as the application type.
However, I always got "Nothing found. Change your search criteria."
I did do some activation work on backend R3 SICF setting. I'm able to directly access web dynpro via http://mywebas.domain:8000/sap/bc/webdynpro/mywd....
If you're using the same scenario, please let me know anything I missed or any other special setting.
Thanks

My Trips and Expenses - Webdynpro ABAP - Change Copy Delete button links

Hello All,
We are using ESS and MSS applications in our scenario. We are using EHP4 version of ECC6.0.
I have configured my homepage framework with custom entries in SAP (resources, services, ... ) and custom Portal content (iviews, pages, ... copied from SAP delivered stuff ). I have a very good understanding of this and I have no issues with the portal navigation and tying my custom homepage framework entries to the custom PCD locations.
The only problem I have is with the Webdynpro ABAP application for "My Trips and Expenses". I can get to this application without any problem.
Within the My Tirps and Expenses application, there are buttons for Displaying, Changing, Copying and Deleting existing Travel Trip Requests and Expense Reports. When I click on any of these buttons, the corresponding page/iview from the standard SAP ESS role is being launched. I would like to point these buttons to my custom page/iview from my custom role.
I did not find any place where I can make this setting. I am not sure how the Service IDs for the standard SAP services are being linked to the application.
I hope some one might have looked into this and any input would be really appreciated.
Thanks,
Raj

I figured this out.
This application makes use of Object Based Navigation and if you adjust the roles assigned to the user accordingly, this will automatically pick up the custom pages form the custom role.
Thanks,
Raj

Webdynpro ABAP webservice call to external server - Cookie issue

Hi,
We are experiencing cookie issue while calling webservice to Tivoli system hosted on IBM websphere.
Steps we have done as follows:
1. Created a ABAP Proxy class from Tivoli WSDL.
2. Configured T-Code LPCONFIG to point to above proxy class and logical port.
3. Configured SM59 RFC connection to point to Tivoli server using basic authentication mechanism (User ID/Password).
4. Called webservice method from WebDynpro ABAP program.
After above steps, we are able to call the webservice method successfully but second time we are experiencing Cookie being adding to the request and eventually no response back to our program.
When we investigated this cookie issue with IBM Websphere people, they says thay have enabled SSO Config instead of basic authentication and that's why a cookie is being added to the request and fails. when they disabled SSO, we are able to call webservic method sucessfully sevaral times. but now this cannot be no longer disabled as other applications are using SSO enable option. So, we are thinking, is there something that can be done in SAP ECC itself as we see the option of using SSO in SM59 instead of User Id/Password but not sure How?
If anybody has undergone this scenario/SSO config from ECC SM59 successfully, Please reply back.
Thanks in advance
Praveen

Here is the link that explains how SSO can be configured in SAP.
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/65/6a563cef658a06e10000000a11405a/frameset.htm
Once done, under Client PSE in Tcode STRUST, you can upload the certificate obtained from the SSO enabled system and use the client PSE (Default) in the SSL Client Certificate area of SM59
I see Thomas has already responded to you and he has written a blog on how to set this up as well.

WebDynpro ABAP vs WebDynpro JAVA for Adobe forms--PCRs--MSS

Hi Experts,
This might be a generic question :
I am modifying PCRs (MSS 1.0,EP 7,ECC 6.0) and now I have come to a point where I need to decide if I have to use Webdynpro JAVA or Webdynpro ABAP for modifying Adobe interactive forms which come with MSS 1.0 out of the box from SAP.
What does SAP suggest??
What do you suggest??
Quick answers appreciated

Hi Aditi,
Thanx for your suggestion but let me just detail what Iam looking for;
I will have to develop a custom PCR for Hire/Rehire (no workflow -- weird right),
now if I develop Adobe forms for this, my question is how am I going to bind these forms to the scenario (QISRSCENARIO).
Whatever is entered in this form is not going through workflow but is going to be directly updated in the database when the manager says SUBMIT.
Usually the HR developer goes to the scenario and selects input by Adobe form and clicks generate, but now if I develop the form using Webdynpro JAVA how am I going to integrate the generated form to that particular scenario.
Sorry if Iam not clear enough, but I really need help in this regard.
Thank you

Webdynpro ABAP or Webdynpro Java?

Hello experts.
I want to learn to develop WebDynpro's
Do you which of the two tools do you recommend? webdynpro java or webdynpro abap.
Greetings

Hi Lupe ,
Although both technologies have same functionalities but even then they are not identical.
Following are some of the differences:
Language :- First difference is the programming language used as the names Webdynpro ABAP and Webdynpro JAVA reflect. In ABAP Webdynpro, along with ABAP coding, RFCu2019s are also supported via Service call. Unlike Webdynpro ABAP, we cannot do ABAP coding in Webdynpro JAVA. Instead RFCu2019s and Web services are created and used in it to serve this purpose. In addition to Web services and adaptive RFC, Java Beans is another model supported by Webdynpro JAVA.
Design Time Environment :- Webdynpro ABAP requires ABAP Workbench (SE80) while SAP Netweaver Developer Studio is necessary for designing Webdynpro JAVA applications. So, additional installation is required. This studio reduces the development effort and utilizes some visual tools for creating components which can be reused.
Storage :- Applications developed using Webdynpro ABAP are stored centrally in ABAP server whereas in case of Webdynpro JAVA, the code remains on the client machine that is developed using a tool called Netweaver Developer studio. So, due to the powerful version control system of Webdynpro ABAP, the load removes from the development machine which is not possible in case of Webdynpro JAVA.
Skills Required :- For Webdynpro ABAP, a developer should have knowledge of ABAP programming, Development tools, Database concepts, ABAP Objects. However, Webdynpro JAVA requires skill set comprising java programming, java development tools and object-oriented concept.
Performance:- Large scale applications that involve large number of web users canu2019t work well on ABAP server. So, for robust and scalable applications, Webdynpro JAVA is preferred because of powerful J2EE server as proved by Sun Microsystems. However, small-scale or applications involving small or medium users can go well with Webdynpro ABAP. Thus, performance varies depending on the number of web users and one can choose ABAP or JAVA accordingly.
So the decession is that its totaly based on your available skillsets and your scenario to be implemented.
Thanks & Regards,
Monishankar C

SM30 Table Maintenance Generator in Webdynpro ABAP

Hi Experts,
I am new to Webdynpro.
Can someone explain me the steps in having the Table maintenace feature in Webdynpro ABAP ?
We are having a custom table in ECC for which the entries will be updated from Webdynpro.
Thanks in Advance,
Regards,
Vivek K

Hi,
for table maintenance in WD4A I prefer ALV grids. Lazy as I am, I'll just point you to this step-by-step scenario ) :
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/3133474a-0801-0010-d692-81827814a5a1?quicklink=index&overridelayout=true
Alternatively you can also make a transaction for the Maintenance view and include the Transaction in the Web Dynpro, but I wouldn't reccomend this..

Questionnaire application in WebDynpro ABAP

Hi,
I would like to design the Questionnaire application in WebDynpro ABAP, which should be in the form of question and answers(4-5) as checkboxes/radio buttons.
For this scenario, how to design the Layout and Node structure?
Thanks and Regards,
Jhansi

Hi Jhansi,
I have created one such reusable component for SAP PPM.
I have used the structure /RPM/TS_QNNR_API.
It has the Question number, desc, and questionnaire group, UI option and has one entry per question per answer options.
For example if Q1 GRp1 has 4 options , it has four entries at runtime with Q1 Grp1 and opt1..opt4.
I have read this table in a node and the dynamically created one node per question.
On the basis of UI option value in the table I created corresponding UI element ( drop down, checkbox grp etc) and bound the node for it.
I will soon be coming with an article on this.
I hope this helps.
Regards,
Sumit

Calling GuidedProcess from WebDynpro ABAP

Hi all
can anybody tell me that how to call GP from webdynpro ABAP.
and what are the advantages and disadvantages in this scenario??
if anyone reply then it would be the great help to me
Regards
Suresh babu

Hey,
You can call a GP from WD ABAP through by implementing a service call from a method that is embedded in your WD. You can refer this link for the same.
http://help.sap.com/saphelp_nwce10/helpdata/en/44/58f9cc0d95311ce10000000a155369/frameset.htm
But you should note here that Data exchange between ABAP WD and GP is not two way but its only one way.
